Day 24 Alexander Miles – 28 days of Black History in Technology

Alexander Miles made improvements to the Electric Elevator patent #371,207 improved the method of the opening and closing of elevator doors.  This was very important because before his invention patrons of the elevator had to close the door manually.  Sometimes this created a situation with bad results because people would not always shut the door, causing accidents with people falling down the elevator shaft.

  1. A great improvement to the elevator system we know today. Thank goodness he filed and received the patent for the eventual upgrades. Your blog posts continue to educate me during this Black History Month.
